Cannot read properties of undefined reading includes

This error message typically occurs when you try to access the includes method of an undefined value. Here are a few possible reasons for encountering this error:

1. The variable you are trying to access is not defined or does not exist.
2. The variable exists, but its value is currently undefined.
3. The variable is defined, but the method you are trying to use is not available for that data type.

To fix this error, you can take the following steps:

1. Ensure that the variable you are trying to access is properly defined and has a value assigned to it.
2. Make sure that the variable is not accidentally reassigned to undefined before using the includes method.
3. Confirm that the method you are trying to use is available for the data type of the variable. For example, the includes method is only available for strings and arrays.

Here's an example of how to handle this error:

let myVariable; // undefined variable

if (typeof myVariable !== 'undefined' && myVariable.includes('some value')) {
  // perform the desired operation
}

In this example, the typeof operator is used to check if the variable is defined before attempting to use the includes method
